<span>If they won the game, they had the greater overall score. That means that they had a final score of 2 goals. The identity property of additions says that if you add 0 to any number, the result will always be that same number. They must have scored 0 goals in the second half, because in the first half they scored 2 goals and at the end of the game they had scored a total of 2 goals. The identity property of addition is the property in the question.</span>
You probably haven't learnt this but the general equations for circle with centre at the origin is x^2+y^2=R^2 where R is the radius of the circle so R^2=(1737+185)^2.I am lazy to press my calculator so type it in yourself.
